There are lots of thrills for kids, and for the region, a much-needed economic boost.

There are 68,000 square feet of indoor water park at the Great Wolf Lodge, including the six-story Howlin' Tornado, and the Wolf Tail Slide with a 360 degree loop and a straight drop down.

The Great Wolf Lodge stands on the site of a former Holiday Inn. Estimates are 100,000 will visit the lodge each year.

There are no day passes there. You've got to stay in one of the 400 suites, many of them with themes.

The most popular is the wolf den.

It's a one stop wonderland, all indoors.

"It's a great family destination experience close to home. You can come have a full vacation experience right down the road," said Susan Storey of Great Wolf Resorts.

Required attire for anyone who works here? Wolf ears.

The city of Fitchburg is banking on the Great Wolf Lodge to explode the tourism trade in the region and bring jobs and tax revenue.

"With 600 jobs, with a $100 million worth of investment throughout the region, this really brings the cake for us because it brings people from outside the region here. This is pure gold for our community," said Fitchburg Mayor Lisa Wong.
